There is only one line of footprints on the snow outside the front door, and the direction is towards the wooden house, after comparison, the footprints are Mao Haitao's, and there are no other footprints around the wooden house.

"Who the hell did it! Yes! ~~~~~", Mao Guangjian raised his head and roared sadly.

"Little stone!"

"Tiger Head!"

"You hurry back now, bring ten brothers over, and bring the servants too!"

"Understood!" , Shi Yuning agreed, and ran out quickly.

There was nothing left on the neat snow, and if there was, it was a white feather lying on the snow.

"How did the murderer get in and how did he get out? It's amazing that there is not a trace left on the snow! ”

Nie Xiaohu squatted down, picked up the feather and looked at it, and stuffed it into his arms casually.

After hearing Mao Haitao's bad news, Yu collapsed all of a sudden, crying bitterly, almost fainting, and Yu Jianji, who was driven down from downstairs, was also stunned by Mao Haitao's death, and was stunned there, until he saw Yu's reaction, he hurriedly ran over to help her.

Mao Kaifeng also cried after hearing the news, his emotions were almost out of control, and finally Mao Guangjian sent him back to the room on the second floor and lay down on the bed.

Cao Xiaohui was shocked and asked Nie Xiaohu about what happened, and after hearing this, she also frowned and shook her head again and again.

"Xiaohui, have you been accompanying Mrs. Yu in the living room? Has she ever been out? ”

"No, I've been with her, she hasn't been anywhere," Cao Xiaohui said, shaking her head.

"What about the two? Yu Jianji and Mao Kaifeng, where are they? ”

"Both of them should be upstairs in their own rooms, I saw them go upstairs with my own eyes, and neither of them came down until you came back, and the stairs were at the back of the living room, and I was sitting right against the stairs, so there was no problem at all."

"Is there anyone else upstairs besides the two of them?"

"No, there are only three people in the family, and they are all busy making lunch in the kitchen at the moment!"

"What? Do you suspect that the killer is someone from his family? Cao Xiaohui asked suspiciously.

"It's unlikely that outsiders will commit crimes," Nie Xiaohu shook his head and said.

"There are no footprints left on the snow around the wooden house, even the snow in the distance I have checked, there are no footprints left, if an outsider commits a crime, unless he can fly, it is impossible to do this, there is only one possibility, that is, the murderer escaped back here after the murder."

"But the wooden house is nearly seven feet away from the backyard, even if the murderer escapes to the backyard, it is impossible not to leave footprints on the snow?"

"I haven't figured this out either, it's really weird!" , Nie Xiaohu said with a frown.

"Is there such a possibility that the murderer stepped on Mao Haitao's footprints into the wooden house?"

"I've verified this a long time ago, it's not possible," Nie Xiaohu shook his head and said, "On Mao Haitao's footprints, the lines on the soles are clearly recognizable, if someone else has stepped on them, the lines on the soles have already been trampled." ”

"Is it possible that the murderer was hiding in the house in the first place, such as the homeless man who slept in the house?"

Nie Xiaohu shook his head gently: "This is also impossible, if this is the case, then how did the murderer leave?" ”

"There is another possibility", Cao Xiaohui said with a frown, "The murderer is a master of using flying knives, and he killed Mao Haitao with a flying knife seven zhang away, so there are no footprints left on the snow?" ”

"I've considered this possibility, but if so, the killer would have been a throwing knife thrown directly in front of the main entrance, because the windows on the left and right sides of the hut were closed, and there was no sign of damage.

But directly in front of the hut was the courtyard wall, and behind the courtyard wall was the pigeon's nest, where I also looked and there were no traces. ”

"Is it possible that the murderer is..."

Cao Xiaohui pointed upwards with her finger: "Throwing knives through the window?" ”

"If this is true, let's go upstairs and see!" , Nie Xiaohu nodded.

Coming upstairs, facing the outside is one side of the corridor, and the other side is the room, a total of three, Nie Xiaohu walked to the place facing the wooden house and stopped.

There is a window in the wall here, and the first thing you see when you look out of the window is the roof of the pigeon's nest, where a few pigeons are standing and cooing, and then you can see the log cabin by the lake in the distance.

"Xiaohui, do you think this is possible?" , Nie Xiaohu pointed to the cabin in the distance and said.

Cao Xiaohui looked at the wooden house by the lake, frowned, and shook her head gently: "The distance is too far, or from top to bottom, there is no such possibility, unless you use a bow and arrow." ”

"But the murder weapon is a dagger," Nie Xiaohu smiled.

"Could it be that the murderer stood here, using icicles as arrow shafts and daggers as arrow clusters, shooting Mao Haitao to death, and the icicles melted immediately?"

"Impossible," Nie Xiaohu shook his head and said, "If that's the case, first of all, the dagger needs to be tied to an icicle, and nothing like a rope was found at the scene; Secondly, the temperature outside was very low, and there was no brazier in the house, the icicles would not melt so quickly, and there were no water stains in the house or on the deceased's body. ”

"Then I really can't think of any other possibility!" , Cao Xiaohui pursed her lips.

Nie Xiaohu frowned and stared at the wooden house for a while, then poked his head out of the window and looked casually to both sides, and suddenly, Nie Xiaohu's gaze was fixed on a wooden ladder leaning against the wall on the right side.

Nie Xiaohu stared at the wooden ladder for a long time, then reached into his arms and felt the feather found in the snow outside the wooden house and looked at it, and then a strange smile appeared on his face.

"Brother Tiger, what's the matter? You ......", Cao Xiaohui's eyes lit up, she already knew that Nie Xiaohu already had the answer in her heart.

"Heavenly ......"

"The secret of heaven cannot be leaked, and it needs to be verified, right?" , Cao Xiaohui said with a smile.

"Exactly!" , Nie Xiaohu snapped his fingers.

"Cousin, several adults, my sister asked me to ask you to go down for lunch", at this time, Yu Jianji came to everyone.

"Good!" , Nie Xiaohu nodded.

After everyone sat down in the living room, Yu Shi looked around at everyone, then opened her bloodless lips and said weakly: "Jian Ji, go upstairs and ask your cousin Kaifeng to come down for dinner." ”

"Got it", Yu Jianji nodded in agreement, got up and went upstairs.

"Auntie, Kaifeng may be a little sad and excessive, his body is already weak, I'm afraid that he won't be able to get the sword alone, I'll help him!" , Mao Guangjian also stood up.

"Go ahead," Yu nodded blankly.

Mao Guangjian immediately followed Yu Jianji upstairs.
